Description

Snare drum end plate and belt

Technical field

The army of the present invention relates to drum, and relate in particular to for the device that will ring string (snare wire) and be installed to the drum body.

Background technology

" drum kit " is comprised of the drum of three types: bass drum, tenor drum and army's drum.Army's drum is the central of drum kit and unusual in function and design.Basic difference is the upper and lower supporting flange of drum body or the design at edge, and drum surface is crossed over its vibration.The upper support edge of army's drum forms around 360 degree even circumferentials (smooth), and the bottom supporting edge has two otch (being generally oval or semicircle) of parallel to each other and the 180 degree location that are separated by.Otch is called as " ring string bed (snare bed) " and changes to some extent on length and the degree of depth according to pattern and/or manufacturer's difference.This forms " arch form " shape of crossing over drum surface, for having kept close contact very important between the drum surface of vibrating and sound string.

Ringing string is one group of coiled metal wire, and it is different on the distance between material (although being steel mostly), coil pitch, metal wire quantity, specification, shape, length, metal wire and integral width.When drum surface and sound string vibrated during playing, these Variable Control amount and the tone color of " ringing string " sound.The end of every group of independent loud string is mounted (often being welding), and to two relative rectangular flats, rectangular flat often is known as " end plate " or " end clips ", its close corresponding otch and the support edge that is positioned at.Each clip is connected on the belt or rope that passes otch and extend along the outside of ladle body, and wherein a belt is connected on the snare strainer, and another belt is connected on the drumstick afterbody (butt-end).The drumstick afterbody remains on a belt on the fixed position with respect to the edge, and another belt can be strained or loosen to take-up device selectively, thereby changes the tension force that rings string.

For most of armies drum, two types end clip design is arranged, the end clip of " trapezoidal " clip and " bending " or " bending ".Can carry out subjectivity between these two kinds of clip design selects.The end clip be designed to ring string as far as possible equably stretching with the center of crossing drum surface and under reach and ring in the string bed.This is so that ring the surperficial close contact of string and drum surface, thereby guarantees " ringing string responds " from the center to the edge.

Traditional two belt-type connectors are difficult to install and regulate.It needs well-proportioned tension force to be applied on each cable end to ring string suitably " in place " and guarantee that all hawsers bear identical tension force in order to make.The single belt method also has its shortcoming.In case belt is through the below of the rear end of clip, it produces the plane of the height different from the rear portion of clip, thereby produces pivot axis and " seesaw " phenomenon, this so that during playing clip to arrive the connection of drum surface unstable with being connected string.Above-mentioned installation method causes the inconsistent of sound and is difficult to suitably regulate.

Summary of the invention

The disclosure is for some schemes of the present invention, and it is preferably not necessarily combination.

A kind of scheme is for the clip of the present invention that connects when making sound string group before ringing string.

Another kind of scheme is for loud string group of the present invention, and it comprises that clip of the present invention is connected the combination that rings string with connection.

Another scheme is for army's tympany string external member, and it comprises the of the present invention or conventional clip that combines with quick-replaceable belt of the present invention.

In another scheme, invented separately rapid belt replacing with respect to the final use of expecting.

Clip comprises the firm plate of rectangle roughly, and it has can connect the front portion that rings string and the rear portion that comprises central area, and central area has the aperture that can connect clamping band.Has the pair of brackets of base of approximate horizontal at the rear portion across central area.When clip places on the base straightly (, the clip that rings string and belt is final to be installed by on drum surface the time when having), base defines the minimum altitude e of clip ₀When base was positioned on the plane, the posterior border position of central area was in the height e of base top ₁The place, and leading edge is positioned at the height e of base top ₂The place.

Army's tympany string group comprises the firm plate of rectangle roughly, and the firm plate of described rectangle has the front portion, comprises rear portion, left side and right side and top and the bottom of the central area with aperture.The rear portion has leg and in the back edge of the rising of central area cross-over connection leg in each side of central area.Installation belt with front end is fixed in the aperture and below the back edge that raises and extends back.A plurality of loud strings are fixed to the bottom of dull and stereotyped front portion and extend forward abreast from the leading edge of flat board.

Army's tympany string external member comprises the firm plate of rectangle roughly, and the firm plate of described rectangle has the rear portion that connects the anterior of sound string and comprise central area, and described central area has elongated hole, and clamping band can connect by described elongated hole.Clamping band has: form the front end of lateral loops (transverse loop), its width is not more than the length in aperture; And pin, its length is greater than the length in aperture and pass ring and maybe can insert by ring.For belt is assembled with ringing the string group, ring and the pin that inserts be placed in the aperture so that the end of pin extend beyond the aperture and be pressed in dull and stereotyped above.

For the present invention, ring aspect the lateral stability of string with the aspect that contacts on drum surface surface, the more even or balance of pressure.This can obtain three kinds of different beneficial effects: (1) is from the pressure that equates of the end to end of clip; (2) in the specific contact that rings between string and the drum surface; (3) ring the quick-replaceable of string.

About the pressure that equates, the clip design of traditional bending and the difference between the present invention be, two bases at the place, rear bight of clip raise the rear portion of clip, thereby have produced bridge with respect to the remainder of clip.Belt is through passing a bridge down, and can not form pivot.Eliminate the horizontal or oscillating motion of loud string, thereby kept the consistance of sound.

Preferred rapid belt replacing with horizontal latch can insert or remove from clip very rapidly.When using preferred belt another advantage be use leverage and the loud string that increases to the downward pressure of drum surface.By making belt through the below of clip rear side, the rear portion of clip is upwards pushed away and is applied the center that downward pressure is crossed clip at the latch of belt ends, rings string to the force value of drum surface thereby increase.

By locate to mention the rear side of clip in the bight, ring the edge that string also is lifted away from drum surface, so that the more close drum surface of contact center, " piston type " motion maximizes and can't discover tone lasting (pitch sustain) about this place's drum surface.This is similar to a large tree, and its trunk (center of drum surface) not have to vibrate (harmonious overtone) and branch (edge of drum surface) constantly at the volley.The height that changes the rear base of clip is controlled this adjusting.The unique advantage of this design be its eliminated with the vibration that rings the hand-to-hand loud string of string bed, having reduced significantly resonance and having rung string hum (sympathetic snare buzz).

It is ring behind loud string that the edge of drum surface is produced by harmonious overtone when decay finishes (after-ring) that resonance rings string hum.Knock and the bulging loud string hum of unwanted resonance that also can cause of the bulging hand-to-hand bucket of army, the drummer regards this as make us angry thing and can not control.The drummer can attempt the whole bag of tricks and eliminate this resonance sound string hum, comprises that detuning bottom drum surface and application belt and other simple and crude shock attenuation device reaches the purpose of eliminating overtone.These methods fail to control fully resonance ring string hum and because they limited the sound potentiality of musical instrument and destroyed the tone character matter of expectation and become further infringement.

Traditional rope and belt compressing method regulate loaded down with trivial details and change to ring string consuming time.This is because connector must unclamp from snare strainer and tail end or anchor, usually need to be such as the instrument of turnscrew or drum lock (drum key).Use the design of improved belt and pin, belt can pass aperture or the slit on the clip, unclamps the two ends that ring string and need not upset the position of belt in two clampers.Thisly do not need performance that tool changing rings string for the drummer who needs to change loud twang sound because of orchestral music form and march form and particularly useful the time is directly involved in the recording studio environment of cost.

Clip 30 is the firm plate form of rectangle roughly, and it has connection maybe can connect the front portion 38 that rings string 20, the rear portion 40 that comprises central area 42, left side 46 and right side 48 and top 50 and bottom 52, and central area 42 has the aperture 44 that can connect clamping band 32.In the pair of brackets 54 of the base with approximate horizontal 56 at rear portion across central area 42.When clip placed on the base 56 straightly, base limited minimum altitude.When clip places on the base, back edge 58 at central area with respect to height e ₀And above base, be positioned at the height e ₁The place.When clip placed on the base straightly, leading edge 60 was at the height e of base ₀The height e of top ₂The place.Preferably, support by the bending rectangle rear bight and then further bending form base 56 and integrally form.Therefore, the back edge 58 of central area 42 is at benchmark or the height of foundation e of base ₀The height e of top ₁Place's cross-over connection support.This height e ₁Should equal at least and be preferably more than the thickness of belt 32, thereby guarantee when tension rings the string parts, back edge 58 can be facing to film pushing belt between base.Like this, apply equal pressure and do not have any swing or inclination by each base 56.

Preferably, clip is formed with the broken line 62 that extends between a left side 46 and right side 48, and it is between aperture 44 and leading edge 60, and central area 42 tilts to extend to broken line 62 from back edge 58.Dull and stereotyped front portion 38 extends to leading edge 60 with the anterior bottom surface 52 ' of basic horizontal from broken line 62, and will ring the end welding, soldering of string or be connected on the bottom surface 52 ' with other conventional methods.In this embodiment, aperture 44 is positioned at the altitude datum e of base 56 ₀Height e with anterior bottom surface 52 ' ₂Between height e ₃The place.

The most obvious among Fig. 7, aperture 44 is partly covered on the aperture along extending on the direction between the dull and

stereotyped side

46,48 and hard auricle (rigid tab) 64 preferably extends upward from the central area 42 at the rear portion of flat board.The aperture has left and right edges 66 and right hand edge 68 and left groove 70 separately and right groove 72, and they extend towards the side of flat board from the edge in aperture.

Such as Figure 4 and 5 the best illustrate, belt 32 preferably is installed is had front end 74, it is fixed in the aperture 44 and below the back edge 58 that raises and extends back.The front end of belt forms horizontal ring 76, and it is positioned at the aperture and has the width of the length that is not more than the aperture.Pin 78 passes ring, and its end is from encircling extension and being supported on respectively in the

groove

70,72 simultaneously.In this structure, when applying pulling force to belt 32 during install ringing the string parts, groove and auricle are held in the aperture environmental protection.

Should be understood that, have or do not have auricle 64 or

groove

70,72 the clip of Fig. 7 all can adopt conventional belt (not shown), this strap lug passes the aperture and passes through comparably central area 42, so that the two ends of a belt all extend to anchor on the ladle body from first clamp, and the two ends of another belt extend to take-up device on the ladle body from second clamp in a conventional manner.For the back edge according to rising of the present invention, even use conventional belt also can remain on height e ₀Thereby the top at the pressure that base 56 places obtain equating, avoided simultaneously very general swing or inclination in the conventional army drum.Similarly, there is not the clip of auricle and/or groove can be at altitude datum e according to of the present invention ₀The height e of top ₂The place provides being connected of the bottom surface that rings string and the front portion of clip, rings the outside surface top that string remains on drum surface thereby make, and avoids thus resonating.

The quick-replaceable that is suitable for ringing string parts 16 at the belt shown in the Figure 4 and 5, by unclamping simply an end that exposes of take-up device, pulling pin 78, and the other end of pushing pin is by the aperture after keeping end, thereby takes off belt fully from the aperture.Another can be installed rapidly ring the string parts by putting upside down aforesaid operations, that is, fully upwards insert an end of pin 78 by the aperture to pass ring and the other end at a certain angle by the aperture, make then that pin is straight so that the end of pin is positioned at groove 70,72.Then reset take-up device and be ready to play drum.This replacing can be finished in less than one minute, yet conventional replacing needs at least 15 minutes.

In another kind of scheme of the present invention, belt 32 can use conventional clip, and it has the aperture 44 shown in Fig. 7, but does not have

groove

70,72 or auricle 64.Except the end of pin 78 is positioned on the plane of conventional clip and does not exist the additional support of auricle 64, install and remove as mentioned above.This embodiment makes it possible to quick-replaceable and rings the string parts, but does not have the advantage of the back edge 58 of rising, and this has been avoided the pressure of 32 pairs of films of belt and same not having to raise the advantage of ringing string 20 above the outside surface of drum surface.Yet quick-replaceable has significant improvement with respect to the present level of the art.

Last a kind of scheme of the present invention may be embodied as army's tympany string external member, it comprises the firm plate of rectangle roughly, the firm plate of this rectangle has the front portion 38 that connects the sound string and the rear portion 40 that comprises central area 42, and central area 42 has elongated hole 44, and clamping band 32 can connect by elongated hole 44.Clamping band 32 has the front end 74 of the lateral loops of forming, and its width is not more than the aperture.Pin 78 is set together with ring or is arranged in the ring, pin 78 length that have greater than the aperture.When the ring with the pin that inserts places in the aperture, the end of pin extend beyond the aperture and be positioned at dull and stereotyped above, remaining belt then by dull and stereotyped antemarginal below.
